Lilium leichtlinii is a perennial bulbous plant in the family Liliaceae, native to East Asia, including Japan, Korea, and parts of northeastern China and the Russian Far East. It is commonly known as Leichtlin’s lily or Citronella lily. The genus name Lilium is the classical Latin word for lily, used since antiquity to describe showy flowering plants of this group, while the species epithet leichtlinii honors the German horticulturist Maximilian Leichtlin, a noted collector and cultivator of lilies in the 19th century. The species grows in grasslands, forest edges, and mountainous regions, where it produces upright stems bearing narrow leaves and nodding, often spotted yellow to orange flowers.

The plant develops underground bulbs composed of fleshy scales that store nutrients and enable perennial growth. These bulbs are the primary edible part of certain Lilium species, including Lilium leichtlinii, particularly in East Asian food traditions. Historically, lily bulbs have been used both as food and in traditional medicine in China, Korea, and Japan, where they are valued for their mild flavor and perceived health benefits.

As a food source, the bulbs of Lilium leichtlinii can be harvested, separated into scales, and cooked in a variety of ways. They are typically used in soups, stir-fries, and simmered dishes, where they develop a soft, slightly crisp texture and a subtly sweet, mildly bitter flavor. In Japanese cuisine, lily bulbs (called yuri-ne meaning lily root) are considered a seasonal and sometimes festive ingredient, often incorporated into clear soups or mixed vegetable dishes. In Chinese cuisine, similar lily bulbs are used in both savory and sweet preparations.

Nutritionally, lily bulbs are composed largely of carbohydrates, particularly starch, along with small amounts of protein, fiber, and micronutrients such as potassium. They also contain bioactive compounds including steroidal saponins, flavonoids, and phenolic compounds, which have been studied for antioxidant and anti-inflammatory properties in experimental settings. Some traditional uses also associate lily bulbs with calming or respiratory-supportive effects, although these claims are primarily based on historical practice rather than modern clinical evidence.
